Specification forming part of Letters Patent No. 10,694, dated March 28, 1854.

T0aZl whom it may concern):

Be it known that I, LUTHIER B. FISHER, of Coldwater, in the county of Branch and State of Michigan, have invehted a new and nseful Improvement in Seed-Drills; and I do hereby declare that the following is afull, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, forming part of this specification, in which Figure lis aplan of the seed-drill, and Fig. 2 is a side elevation of the same.

Similar characters of reference in the several figures denote the same part of the apparatus.

My invention, which refers to drills of a triangnlar form of frame operated bya wheel at the head of the implement, consists in 50 attaching the regnlating-wheel that by the operation of turning the drill the teeth are raised from the earth and the discharge of seed stopped. The particular arrangement Will be understood by reference to the drawings, in which A represents the sides of the frame, held firmly together by th eross-piece B and beam C. The rear of the frame is supported by the wheels D, upon the axle E, loosely attached under the side A by the rods a. (Shown loy red lines in Figs. 1 and 2.) In front of the frame is the wheel F, having on one side the cam G. This wheel turns on the axle I), and is attached to the frame by the clevis 0, which passes above and below the beam C, and is held by the pin (1, running through clevis and beam. Embracing the cam G is the slotted recessed plate f, its rear extremity terminating in a hook, h, to which is attached the rods z, oonnecting With the discharging-slides.

Fastened beneath the side pieces, A, are the drill-tubes T, communicating by openings m with the hoppers or receptacles for the grain. These may be of any of the known forms, With any arrangement for regnlating the delivery of the grain that may be found best suited to the end in view. Under the beam 0 runs the bar 19, its front end fastened to the pin d, andthe rear extremity attached to the short arm of the lever Q, which has its fulcrum at r on the cross-piece B. This bar is slotted at q, to pass over the fore tooth, and has a short distance in rear of the pin (Z a depression, 8, the use of which Will be hereinafter described. On the edge of the axle E are the notches 25, to retain the lever Q in any desired position. The pin (2 passes through a slot in the beam 0, as shown in red lines, Fig. 2, so that the drawing of the bar 29 to the rear inclines backward the pin and raises the front of the beam..

Th operation of my improvement is, as follows: The forward movement of the apparatus causes the reciprocating motion imparted to the plate f by the cam G to be communicated to the slides y 3 for regulating, by any of the well-known methods, the distribution -of the grain. When the extremity of the field is reached, the wheel F is drawn around at right angles to the b'eam 0, the clevis c and recessed plate f turning about the pin d and bock h, and the reciprocating motion of the plate producing no other effect than giving the point of attachment of the rods to the hook h a slight lateral movement, the slides y y remaining entirely at rest longitudinally dnring the turningL As the clevis is drawn around perpendicular to the beam its lower branch slides under the depression 8 of the barp and raises the front tooth from the ground. VVhenthe turning is completed, the recipr0cating motion of the plate f is transmitted to the slides y y, the front of the implement falls to its nsuallevel and the drilling proceeds as before. When it is desired to raise the fore part ofthe drill during its progress, the lever Q is moved, as indicated by the arrow, drawing the bar p to the rear, and, by its connection with the pin d, inclining its lower extremity backward. This causes the frame to rise upon its 'rear wheels as a fulcrum, the front of the beam being elevated proportional to the movement of the lever Q.

The simple operation of this implement is due to the pivoted attachment of the drivinggear and the clevis attachment of the pro pelling-wheel, in connection With the rod 12 and movable pin d. The manner of operating the slides may be varied t0 suit the operator, as well as the description of grain to be sown;

I do not claim the form of the frame or the method of operating the slides; but

What I do claim as my invention, and desire to secure by Letters Patent, is-* 1. The-combination of the rod p, lever Q, clevis c, and pin d, when the latter is movable in a longitudinal slot for raising the teeth Intestimony whereofI havehereunto signed from the ground, as herein fully setforth. 1 my name before WO subscribing Wihnesses.

2. The aocaebment of the rods z opemtin the slides, 130 the hook 7L, as deseried, s0 thaz LUTHER FISHER' the slides Wi11 reman at resta during the tuming of the implement, as herein fu11y set forth.
